' This inventionrelates generallyhtodoor" r latch constructions and re ers more particularly to .the outside handle and rollback assembles ofvehicle door latches.

5 One of the essential objects of the invention is to provide an assembl of th s type wherein means is provided or taklng up,

play between the rollback and'handle stem and for holding the stem and handle in a 9 predetermined position when the parts are I installed on the vehicle door.;

Another object. is to provide an, assembly which can be economically manufactured an easily and quicklyyinstalled. 7

tails of construction of this invention will be made more apparent asthis description proceeds, especially when considered in con-, nection with the accompanying drawing,

tional rollback on the stem'10 between the plates 8 'and2 and operable by thestem'and handle to effect a retraction of the :bolt 4 In the present instance the rollback 11 comprises three sections A, B and C respectively arranged side by side on the stem 10." Preferably the sections A and C are similar I andare formed fromrrelatively heavy gage sheet metal. As shown, these sections have 50 circular recesses 14, and 15frespectively opposing eachother and forming a central chamber D and have laterally projecting circular hub portions 16 and 17 respectively in alignment with said recessesl land 15 and;

journaled in aligned openings 18 and "19 respectively in the plates2 and 8. The sections A and C valso have overlapping upstanding complementary arm portions 20 and '21 [respectively that are normally engaged by a shoulder 22 of the spring pressed bolt shank 5 and are heldthereby against the lateral flange 3 of the case plate. In this connection it will be noted that the arm spor- .tions;20.and 21 are in alignment when the 2 stem receiving openings 23 and 24 {therein I are in registration. The section B is c'ircular and fits snugly within the chamber ,1)

formed by the opposed recesses 14 and 15. I

Preferably this section 'B is formed from light gage spring metal and is provided Eat one side with a vertical web-25 havin :a sub,

stantially square opening 26 receiving the stem 10 and having four lugs27 inclmi from the edges of the square opening 26an yieldably engaging the four sides of the stem 10. The section Bis also provided at sub-- stantially diametrically opposite pointsv I rectangularshaped notches 30 -and 31 respectively that receive correspondingly shaped lugs 32and' 33 respectively at diametrically opposite In use the lugs32 and 33constitute stops for holding the section B} in correct relation to the sections A and C, and the lugs 27 are under tension and-bear firmlyagainst the I stem 10 of the handle, hence when'the shoulder 22 of the spring pressed bolt shank 5' 7 bears against the arm portions 20 andf21 of no the sections A and C the intermediate section B will take up any play between the sections and stem and the latter and the handle 9 will be held in a horizontal position.
